The T12 sting mill station on the STM32 controller v2.1S version of 2019
- Price: $44.26 (at the time of publication)
Somewhat unexpectedly, I was offered a KSGER soldering station based on the new version of the v2.1S controller, which uses a pulse stabilizer instead of a linear converter for secondary power. Since there were no reviews for this version, I was seduced, eventually getting a station that was excellent in all the components from the purchased on their own. In addition to the new controller in it is a power supply of a new sample, and the body is plastic against my metal. In the review I will try to compare all these components. Spoiler: a controller on a faster processor, with a different OU and a battery backup problem.
A little preamble. In the comments to my review sancho1971 brought a photo of the new version of the controller, which has already got a few Muskows. He did not do the review, confining himself to the discussion in the comments. At the same time, some points remained incomprehensible to me. At the same time, I showed the review to the seller as proof that the power supply does not withstand the stated current (I had a slight argument with him before buying his station), and the scheme of powering the controller is not onthe "fen" date. To which in response and received an offer to test a new version of the controller with a new BP.
Next, I will refer to the station from the previous review more than once, because in addition to the work in general I want to highlight the differences between the "new" version and the "old one".
The traditional part in such reviews is about a parcel with organoleptic assessments under a spoiler.



The body size is 156 mm long (150 mm body q two end panels), 87 mm wide, 39 mm height without legs or 44 mm with legs.
In total, I was sent "Sets 4" in the terminology of the store - in addition to the station and pens a la FX-9501 in the set includes three more stings (K, D16 and JL02) in the branded bags. The sting is no different and there have already been reviews on them, so I will not write about them. They work, calibrate, fall down.
What surprised me - there is a guide in the set! In Russian and English. Short, but informative. Really... From the old version of the controller 2.01. :) Well, sometimes the curve translation, sometimes not the description, and sometimes just missing the text (in the menu of temperature compensation cold sleeping Cool End). However, this is a positive development.


Before turning on, I would advise to check the build quality, because in the reviews at different stations there are interesting situations, up to the inserted pin in the connector, which led to a short circuit, touching the body from the inside.
I'll start with the pen. Collected it a little hastily, without twisting until the end of the GX12 connector, the plastic part rotates freely. Pike looks normal. Contacts are not isolated, and there are often fears that in this case the wiring may be shortened to the body at some body movements, or two contacts are short nearby. For some reason, the Chinese forget to install a large "Cambrick" which is included in the kit to the GX12 connectors (at least to my three, received from this store in other kits, included). It can be seen on the top connector. This cambrick is enough to isolate the wires from the hull. From closing two neighboring contacts, it will not save, but the backlash of contacts is not so large that with a similar ration, when the insulation rests on contact, there was a closure.
With a ration cartridge in the handle, too, not all is well. The pike is normal, but the wire is cleaned quite strongly, as a result, the screed fixes not the external insulation of the cable, but only the internal wires. This is a serious disadvantage for the product, which is constantly on the move.
To see the assembly from the inside, you need to disassemble the case. And then involuntarily you start to compare it with metal. You can immediately see the first difference - the front panel is glued with a stiletto, which closes and screws. To disassemble it will need to carefully pick it up with something sharp. The second difference - if the back panel is attached to the screws, which are twisted into metal sleeves on plastic halves, the front - on screws just in plastic.
Also, by attaching the end panels only at the corners when removing the power cord 220B the back panel is significantly bent, which undermines the impression of the "monolithic" of the case. There is no such feature with metal.
What's inside. Components - as promised, a new version of the BP and a fresh version of the controller. Connected to each other through connectors, with two, both on the controller, and on the BP. Both XH 2.54-type connectors with a maximum current of 3 A. Pad 220B with a fuse socket (set at 5 A) are also connected by a connector, but already more powerful (although the currents are noticeably smaller). The controller board is now attached not just for the encoder, the GX12 connector is falling into it, at the same time forming a second anchorage point. As a result, the "hardness" of the design here is better than in the previous version, but it is more difficult to remove the controller from the front panel. Either to plough the GX12, or to break the board on the holes, the benefit of this opportunity provided when tracing. The board of the power supply is attached to the body by two small screws (although there are four fastening holes), for which there are sleeves on the body.
Otherwise, no "snot" or "flop" is not noticed, the battery of the watch is present, connected by a small connector, fixed with glue directly to the bottom half of the case. It is also noticeable that the controller board is not fixed parallel to the front-facing plane. Well, and nipic - confused the colors of wires at the power connectors, black here "plus" and red "minus."




And then there is an oddity - back to connect the halves of the body can not, the top is already the bottom half about the thickness of the wall. Plus, I couldn't insert the top half into the front-panel notch, so I couldn't get the case back without cracks. I already wanted to pick up epithets about how you can make two identical details so crooked, and about "Chinese Cinderella", who managed to pull the shoe on the leg of his sister to combine the two halves of the body, but accidentally noticed the reason.
The reason is banal. The hull of the station inside is already than the power supply board. If the board has a size of 83.2 mm, the body inside by a millimeter is already - 82.2 mm. And when you insert a power supply, the plastic case just bursts to the sides.
Since the edges of the BP board do not contain tracks unlike the old one (it has thin strips of grounding at the edges, in order to ground the body), boldly take the nadophile and grind the "side" board to the white stripes of silkscreen. As a result, we get a dimension of 82.0 mm, and the board easily gets up in the body without deformation. By the way, the metal body board quietly enters without a rest.
It would seem that the "hurrah" halves of the body are now perfectly combined. Yes, but the problem of mismatch between the two halves of the case and the notch under them on the front panel remained. Plus interferes with the shoulder on the front panel (even when I took out all the boards, the case because of it did not converge). It should be carefully cut with a scalpel. But even without it, just to collect the body back still does not work, you have to press, pull and make other efforts to the body converged. Alas, the corps is "out of the place."
It's time to turn on the station. First, no handle. What can be noted immediately from the changes:



The rest of us has the same version of firmware 2.10 and the version of iron 2.1S, menu and management are no different (I think there is no point in repeating more than once here described). The encoder works clearly.
With a connected soldering iron at the station, the temperature readings are a little dancing. This is especially noticeable in standby mode, which I put at 120 degrees Celsius. If the previous station readings almost do not move, only occasionally slips 121, then here constant dances 120-122, sometimes 123 slips. The same is the same in the mode of maintaining the working temperature, although there is already a "amplitude" of only 2 degrees. On animation you can compare the behavior of stations, from above old, from below new.

Impressions from the station as a whole
It's time to turn on the station. First, no handle. What can be noted immediately from the changes:
- The beeper's squeak is much quieter and not annoying, as in the previous version of the controller;
- The screen is much brighter (the glass is not so dark);
- Watch... Do not work, every time starts from 00:00 (complete battery planted at zero);
- ERROR message without a connected soldering iron hangs steadily, no phantom temperature readings;
- viewing angles are worse because the screen is noticeably deeper behind the glass.
